Posted in Implementing Highcharts in RoR

You have been a great help Jacob...

Probably where I am struggling is how to structure the code in RoR...

For example, I assume I draw the chart in the main HTML page, then when they filter the data I use a javascript callback to change the data?

The way I had it before was redrawing everything and I know there has to be a more efficient way to do it...

That helps... I want to replace a series vs adding a point, so I assume I would have to do a chart.redraw(); ?

I've had them working this way before, however the part I struggle with is dynamically updating the data without redrawing the entire page. I use Filterrific to filter the data.

I guess I am looking for the most efficient way to do it in RoR.

Looking for the best way to implement Highcharts in RoR. I have been spoiled by ChartKick however one of the features I need in HighCharts is the Drilldowns and the maker of ChartKick said "it's a neat concept but outside the scope of ChartKick".

Has anyone worked with HighCharts and can point me in the right direction?

Maybe Chris can do an Episode or 3 on the subject... :-)

Posted in Struggling with an association test

I have a project that has a User, a Building, and a Role
There is a building_roles table that is user_id, building_id, and role_id
Then I have a has_many :users through building_roles
There is a validation on the user that verifies it must have at least one role in a building

Can't for the life of me get the association to work in a factory for testing

Anyone done this before?

I have an app designed that I have classrooms and I want to "enroll" students in the class en mass. For example I want to be able to search by name and either add by an enroll or add button or a checkbox...

Any suggestions on examples or can anyone suggest the best way to do this?
